The stadium owners need to find the optimum price
for the games.

What are the coefficients of elasticity of supply
and demand if the price is raised from $6 to $8? (8 points)
b.
Characterize the demand and supply for tickets
based on the calculated elasticies. (4 points)
c.What is the optimum price
that the stadium owners can set for the tickets? (4 points)
d.
Why is the selected price for the tickets better
than other prices given in the table above? (4 points)

4.(TCO C) Answer the next questions (Parts A and B)
on the basis of the following cost data for a firm operating in pure
competition:

OUTPUT —— TFC ———- TVC
0
$500.00 0.00
1

500.00 70.00
2
500.00 130.00

(a.) (15 points) Refer to the above data. If the
product price is $185 at its optimal output, will the firm realize an economic
profit, break even, or incur an economic loss? How much will the profit or loss
be? Show all calculations.

(b.) (15 points) Refer to the above data. If the product price is $200
at its optimal output, will the firm realize an economic profit, break even, or
incur an economic loss? How much will the profit or loss be? Show all
calculations. (Points : 30)

5.(TCO D) A software producer
has fixed costs of $30,000 per month and her Total Variable Costs (TVC) as a
function of output Q are given below:

33,000 80,000 2

43,000
120,000 1
(a.) (15 points) If software can only be produced
in the quantities above, what should be the production level if the producer
operates in a monopolistic competitive market where the price of software at
each possible quantity is also listed above? Why? (Show all work.)
(b.) (15 points) What should be the production
level if fixed costs rose to $50,000 per month? Explain.

6.(TCO F)

(a.) (20 points) Suppose nominal GDP in 1999
was $100 billion and in 2001 it was $260 billion. The general price index
in 1999 was 100, and in 2001 it was 180. Between 1999 and 2001, the real GDP
rose by what percent?

(b.) Use the following scenario to answer
questions (b1) and (b2).
In a given year in the United States, the total
number of residents is 230 million, the number of residents under the age of 16
is 38 million, the number of institutionalized adults is 15 million, the number
of adults who are not looking for work is 27 million, and the number of
unemployed is 12 million.

(b1.) (5 points) Refer to the data in
the above scenario. What is the size of the labor force in the United States
for the given year?

(b2.) (5 points) Refer to the data in the above
scenario. What is the unemployment rate in the United States for the given
year? (Points : 30)

7.(TCO G and H)

(a.) (15 points) What are the arguments for and
against the use of fiscal policy to fight inflation, lower unemployment, and
raise GDP (Keynesian and Monetarist)?

(b.) (10 points) Any change in the economy’s
total expenditures would be expected to translate into a change in GDP that was
larger than the initial change in spending. This phenomenon is known as
the multiplier effect.Explain how the multiplier effect
works.

(c.) (15 points) You are told that 80 cents out of every extra dollar
pumped into the economy goes toward consumption (as opposed to saving).
Estimate the GDP impact of a positive change in government spending that equals
$10 billion. (Points : 40)

8.(TCO G)

(a.) Reserve requirement for banks is set at 5%.
Your firm deposits its profits of $28,000 into the Third National Bank.

(10 points) How much excess reserve does your
deposit generate for the bank?

(10 points) What is the maximum amount of new
money that can be created in the banking system as a result of this deposit?
Show all work.

(b.) (10 points) What is the Federal Funds Rate
in the banking system?

(10 points) Explain how the Fed manipulates this rate in order to
achieve macroeconomic objectives. (Points : 40)

9.(TCOs E and I) Let the exchange rate be
defined as the number of dollars per Japanese yen. Assume that there is a
relatively lower rate of inflation in the U.S. relative to that of Japan.

(a.) (10 points) Would this event cause the
demand for the dollar to increase or decrease relative to the demand for the
yen? Why?

(b.) (10 points) Has the dollar appreciated or
depreciated in value relative to the yen?

(c.) (10 points) Does this change in the value of
the dollar make imports cheaper or more expensive for Americans? Are American
exports cheaper or more expensive for importers of U.S. goods in Japan?
Illustrate by showing the price of a U.S. e-reader in Japan, before and after
the change in the exchange rate.

(d.) (10 points) If you had a business exporting goods to Japan, and
U.S. inflation fell as discussed above in this example, would you plan to
expand production or cut back? Why? (Points : 40)
